Mitotic crossing-over induced by two commercial herbicides in diploid strains of the fungus Aspergillus nidulans

R. A. Cardoso, Pires, L. T. A., Zucchi, T. D., Zucchi, F. D., and Zucchi, T. M. A. D., Mitotic crossing-over induced by two commercial herbicides in diploid strains of the fungus Aspergillus nidulans, vol. 9, pp. 231-238, 2010.

Some herbicides are suspected of promoting teratogenic, carcinogenic and mutagenic events. Detection of induced mitotic crossing-over has proven to be an indirect way of testing the carcinogenic properties of suspicious substances, because mitotic crossing-over is involved in the multistep process of carcinogenesis. We examined mitotic crossing-over induced by two commercial herbicides (diuron and trifluralin) in diploid strains of Aspergillus nidulans based on the homozygotization index.

Induction of mitotic crossing-over in diploid strains of Aspergillus nidulans using low-dose X-rays

L. B. Stoll, Cremonesi, F. C. A., Pires, L. T. A., Zucchi, T. D., and Zucchi, T. M. A. D., Induction of mitotic crossing-over in diploid strains of Aspergillus nidulans using low-dose X-rays, vol. 7, pp. 467-475, 2008.

As a contribution towards detecting the genetic effects of low doses of genotoxic physical agents, this paper deals with the consequences of low-dose X-rays in the Aspergillus nidulans genome. The irradiation doses studied were those commonly used in dental clinics (1-5 cGy).

Aspergillus nidulans as a biological system to detect the genotoxic effects of mercury fumes on eukaryotes

G. D. Sousa, Zucchi, T. D., Zucchi, F. D., Miller, R. G., Anjos, R. M. A., Poli, P., and Zucchi, T. M. A. D., Aspergillus nidulans as a biological system to detect the genotoxic effects of mercury fumes on eukaryotes, vol. 8, pp. 404-413, 2009.

Mercury (Hg) pollution is one of the most serious environmental problems. Due to public concern prompted by the symptoms displayed by people who consumed contaminated fish in Minamata, Japan in 1956, Hg pollution has since been kept under constant surveillance. However, despite considerable accumulation of knowledge on the noxious effects of ingested or inhaled Hg, especially for humans, there is virtually nothing known about the genotoxic effects of Hg.
